WATER-BAG SYRINGE.

SPECIFICATION forming part 0f Letters atent N0. 675,897, dated Jun@ l 1,1901.

Application filed October 17,1900. Serial NoA 33,370. (No model.)

To @ZZ whom t may concern:

Be it known that I, WILLIAM D. MARTIN, residing at Warsaw, in the countyof Vyoming and State of New York, have invented certain new and usefulImprovements in Vater-Bag Syringes, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to syringes for sanitary purposes, known as waterbag syringes.

The object of the invention is to produce a syringe by attachments tothe ordinary ilexible water-bag without in any wise mutilating thebagg'and the invention consists in certain constructions andcombinations of parts by which this water-bag syringe is produced.

Figure l is a side elevation of the waterbag syringe ready for use. Fig.2 is a side elevation of the nozzle and support. Fig. 3 is a section,and Fig. 4a plan, thereof. Fig.

is a broken detail section and partial elevation of the stopper andconnections.

A indicatesa Well-known form of waterbag, usually of rubber or rubbercloth and having a funnel mouth B; but the latter is not essential. Thebag illustrated has the usual screw-threaded mouth C, into which astopper is screwed. For use as a syringe a perforate screw-threadedstopper D is provided, and this stopper may have a rubber gasket E tosecure tight closure between cap F of the stopper and the Inouth of thebag. The stopper D preferably has a polygonal portion Il to permit afirm grasp by the hand or a tool. A nipple I at the end of the stopperpermits the attachment of a flexible tube K thereto. lVhen the perforatestopper and tube or hose are attached, the water or liquid with whichthe bag is supposed to be filled can be ejected through the tube K bypressure on the bag. A closing-valve should preferably be provided, andfor convenience I use a clamp L, by which the flexible hose may becompressed and stopped. With the perforate plug, tube, and valve the bagmay be used for many of the sanitary purposes of the sick-room.

A nozzle-support M is provided for attachment to tube K. Thisnozzle-support may be of Wood, hard rubber, or other suitable material,having a broad base M/ and a side pipe or passage M2, to which side pipethe tube or hose K is attached. The passage M3 through this side pipeextends upwardly through the nozzle-support, which support terminates ina screw-threaded nipple M.

The common straight injector-nozzle O of a syringe of usual constructioncan be readily attached to this screw-threaded nipple. Other well-knownforms of syringe-nozzles may be substituted, as with the usual syri ngefor hospital and sick-room use.

As nearly every family has a water-bag and a syringe, it is necessary toadd but little thereto in order to make an efficient waterbag syringe.

The device assembled for use is shown in Fig. 1. The hosetube K isconnected to the bag and nozzle-support in the manner shown. Thenozzle-support is placed on top of the filled water-bag. The person touse the syringe seats himself on the water-bag with the syringe nozzleentering the rectum. The Weight of the person on the bag will forciblypropel the water or [luid contents of the bag through the hose-tube andnozzle, and the pressure can be increased until the full weight of thepatient is employed as a propelling agent, if necessary.

I am aware that a water-bag syringe has been used in which the nozzle isconnected tolthe side of the bag. This is objectionable, as the bag isto some extent rendered useless for other purposes. My attachment in nowise injures the water-bag for ordinary uses. When in use as a syringe,the How of liquid through the hose-tube K can be controlled by the useof clamp or compress L.

Vhat I claim is- I 1. A water-bag syringe consisting essentially of awater-tight bag of usual construction, having imperforate sides, aflexible tube connected to its removable perforate stopper, anozzle-support with a broad base and side pipe to which the said tube isdirectly connected, and thc nozzle connected to said support, wherebythe nozzle-support resting on the bag serves as a means for compressingthe same, all combined substantially as described.

2. The combination, in a water-bag syringe, of a tube connected toaremovable perforate stopperat the mouth of the bag, abroad-based IOOnozzle-support connected to the tube and having its base adapted to reston the imperforate side of the bag, and a removable injector-nozzle onsaid support, substantially as described.

3. The nozzle-support for connection to a water-bag, having a side pipefor connection to the hose, a broad base, and a threaded nippleextending upward to receive the detachable injector-nozzle.

4. The attachment by which a water-bag; may be made into a water-bagsyringe, said attachment consisting of a perforate stopper having meansfor holding it tightly in the mouth of the bag, a flexible tubeconnected x5 to said stopper, a nozzle-support having a broadsubstantially flat base, and connected at the side to said flexibletube, said nozzlesupport having a passage from said tube, and means forattaching the injector-nozzle, all 2o substantially as described.

In testimony whereof I ailix my signature in presence of two witnesses.
